Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.

Mica powder is derived from natural mica, which is mined from various locations around the globe, with significant deposits found in India, China, and the United States. The natural mica is processed to create a fine powder, which possesses a range of iridescent colors and a shimmering quality that is highly sought after. The powder is categorized based on its particle size and color, and it can be treated to achieve different finishes, including matte and glossy effects.

Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.

Mica powder is derived from natural minerals found within the earth’s crust. Mica itself is a group of silicate minerals characterized by their ability to form thin sheets. When processed, these sheets are ground into a fine powder, yielding a product that sparkles in the light. The natural reflectivity and translucence of mica powder make it an ideal additive for car paints, enabling a range of vibrant colors and finishes.

White mica is more than just a mineral; it is a bridge between the earth's geological history and modern human creativity. Its formation processes, remarkable properties, wide-ranging industrial applications, and cultural significance contribute to its allure. As we explore the multifaceted nature of white mica, we gain a deeper appreciation for the intricate relationship between nature and humanity. In a world where synthetic materials often dominate, white mica stands as a reminder of the beauty and utility that nature provides, sparkling and shimmering in the light of both art and industry.

For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.

X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.  

นอกจากการใช้งานที่ได้กล่าวมาแล้ว ผงมิก้ายังมีบทบาทในอุตสาหกรรมอื่น ๆ เช่น การผลิตเส้นใยและวัสดุที่มีความยืดหยุ่น เช่น สายไฟ เนื่องจากมิก้าเป็นวัสดุที่ไม่สามารถนำไฟฟ้าได้ จึงช่วยเพิ่มคุณสมบัติการเป็นฉนวนได้เป็นอย่างดี
